Radio link management in distributed network architecture

摘要

In a mobile communication network, the call context for an active call is managed in a distributed manner following a cell change. When a mobile station migrates from one access node (AN) to another during the course of a call, the call state variables are transferred to the new serving AN. Additionally, a mapping table is transferred to the new serving AN indicating the location of buffered data. The mapping table reduces the amount of data that needs to be transferred to the new serving AN.
